MACHINE FOR MAKING BROOM BUNDLES OR, UNITS.

Application filed May 14,

To all whom it may concern:

Be it known that I, HARRY D. Nnrr, a citizen of the United States, and resident of Cambridge, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Machines for Making Broom Bundles or Units, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My present invention relates to brooms or brushes, and more particularly to machines for making broom or brush bundles or units.

In my Patent No. 1,367,753, dated Feb. 5, 1921, I have described and claimed an 1 improved form of broom or brush in which a plurality of units or bundles of fibre are arranged in a holder, and in my Patent No. 1,411,221, dated March 28, 1922, I have described and claimed the novel features of a unit or bundle adapted to be used in the holder of said first named application,

while in my Patent No. 1,421,812, dated July. 4, 1922, I have described and claimed the novel features or" the construction and arrangement of parts of a machine used in the manufacture of broom units or bundles and particularly for completing thetoperation of placing the binding band in position thereon. The machine forming the subject matter of my present invention may be used in conjunction with the machine last referred to, and its function is to partially complete broom or brush units by positioning binding bands thereon, such binding bands being deformed by the machine to an extent sufficient to enable them to maintain their position on the broom or brush unit. In this partially completed condition the brush or broom bundles are fed to the machine above referred to, where the binding band is pressed into the proper size and shape.

The principal object of my invention therefore, is an improved broom or brush unit or bundle making machine.

Another object is an improved device for crimping the binding band of a broom or brush unit or bundle.

Other objects and novel features of the construction and arrangement of parts con- 1921. Serial in. 469,736.-

stituting the machine will appear as the description of the invention progresses.

In the accompanying drawings illustrating the preferred embodiments of my invention,

Fig. 1 is a side elevation,

Fig. 2 is a. sectional plan View on the line'2-2 of Fig. 1,

Fig. 3 is an and elevation with the sliding block removed,

F 4 is a plan View of a modification, Fig. 5 isa view of a band before crimp- 111g Fig. 6 is a view of the band after crimp ing, and

Fig. 7 is a perspective view of a unit or bundle as made by the machine.

Referring to the drawings, 10 designates a base on which is secured, in any suitable manner, a rectangular block 11, provided with a recess 12, a counterbored portion 13, and a perforation 14, all lying in the same axis. The diameter of the counterbored portion 13 is slightly greater than the external diameter of a band 15 adapted to be crrmped, as at 16, to encircle and grip a unit or bundle 17 of fibres, such as broom corn, bristles or the like, while the diameter of the perforation 14 is less than the diameter of the portion 13 and equal in diameter to the smallest diameter of the funnel shaped opening 18 in a block 19, this block 19, either. solid or split into two sectlons, as shown in the drawings, being an easy sliding fit in the recess 12. Longitu dinal slots 20 diametrically arranged in the block 11 with respect to the counterbored portion 13, each communicate, by means of a hole 21, with a hole 22 in which is slidably mounted a round ended plug 23, a coil spring 24, between the inner end of the plug 23 and the bottom of the hole 22 tending to force the plug 23 outwardly, as clearly shown in Fig. 2. Attached to the plug 23, by a member 25, is a crimping tool 26, which is slidably mounted in the longitudinal slot 20. Pivotally mounted in the members 32 on the block 11 by screws 27 is a lever 28 provided with a handle 29, each leg of the lever being pro vided with a round headed bolt 30, secured to the lever by a nut 31, the rounded end of said bolts engaging with the round ended plugs 28 to force the crimping tools 26 inwardly into the counterbored portion 13, as shown in Fig. 2. A plate 37, at tached to the back oi the block 11 by bolts 33, acts as a stop tor materiel placed in the machine.

To operate the machine, the lever 28 is moved to the left, 218 shown in F 1, to more the bolts 30 out of engagement with the round ended plugs 23, when the springs P2 1 move the crimping tools 26 out of the counterbored portions 13. The block 19 is removed from the recess 12, one of the bonds 15 inserted in the counter-cored portion 1;), and the block it) replaced in the recess. Enough fibres, such as broom corn, or the like, to form a unit or bundle 1.7 is forced into the funnel shaped opening 18, through the band 15 and the perforation 1d against the plate 37. The lever :28 is swung to the right, as viewed in Fig. 2, when the bolts 30 engage with the round ended plugs 23 to force the crimping tools into the counterbored portion 13 to form the crimps 1G in the band 15, as shown in Fig. 3, in this manner causing the band 15 to engage the libres and form a broom or brush unit or bundle.

Referring to Fig. l, showing at modification of my invention, 10 designates the base having a block 34: mounted thereon. in which is located a counterbored portion 13,-s PGF- oration 141, and all elements above described as being associated with the block 11, being in like manner associated with the block 3%, except that in the present modification there is no sliding block 19. In place thereof 1 pivotelly mount, on vertical. axes on either side of the front of the block Set, two blocks 35 and 36, in each of which is formed one half of a funnel shaped orilice, the small diameter of this orifice being equal to the diameter of the perforation 14. "he only difference in the operation of this modification over that of the forms described above, is that the blocks 35 and 36 are swung on their pivots into the dotted position shown in Fig. 4:, to expose the counterbored pori ieinw tion 13 for the insertion oi the bands 15.

While I have described the preferred embodiments of my invention somewhat in detail, it to be understood that I may vary the size, elmpe and arrangement of parts constitutino' my improved machine within wide limits wi hout departing "lroin the spirit of the invention.

1121311152, thus described my invention, what I claim as new is:
